Clek isn’t a well-known brand, but they’re certainly starting to make their mark when it comes to safety. We tested the Clek Fllo and found it to be impressive, but it comes with a high price tag.

The Clek Fllo can accommodate children up to 50 pounds, but in order to use it for an infant, you have to purchase the newborn insert. If you don’t plan to purchase this add-on, then you have to wait until your child can sit up unassisted before using it. We didn’t really like that. 

Furthermore, the safety ratings are the only good aspect of this car seat. It is designed to mimic an adult car seat with a steel-reinforced frame and energy-absorbing crumple zones. These are meant to absorb the impact of a car accident. It also has the highest rear-facing weight limit in North America. 

We found out that there are multiple models that have different advantages. This particular model is standard and the cover does not come off. You have to wash it by hand. If you choose the model with the Crypton Super Fabric, it’s practically indestructible and GREENGUARD Select Certified. Unfortunately, it costs more. 

In all honesty, we don’t recommend this car seat. Not only is it pricey, but there’s nothing special about it other than the fancy safety ratings. You have to purchase add-ons if you want to use it for an infant and by the time they are able to sit up on their own, you only have another couple of years until you need a new seat. To us, it’s just useless.

Unique Features

Certain features make this car seat unique from others on the market. This car seat is narrow.

Why is This Important?

The founder of the company initially wanted three children, so it was vital they were able to fit three car seats across in a standard vehicle. Keeping a car seat clean is a difficult task. The Clek Fllo makes it a little easier. If you choose a Fllo in a Crypton Super Fabric, you get to enjoy the benefits of a GREENGUARD Select Certified fabric.

What exactly does this mean? It means the fabric is practically indestructible. It repels stains and moisture. It prevents the build-up of odor-causing bacteria. You’ll never have to fear spilled milk again. Keep in mind: this extraordinary fabric can only be hand washed.

Pros and Cons

We all know how important it is to have a car seat rear-facing. Federal guidelines keep extending the age limit for it. This is great – and the Clek Fllo is the right car seat for the job.

The Fllo can accommodate children up to 50 pounds rear-facing.If you have or are planning on a big family, you’re going to want to check the Fllo out. Thanks to its narrow frame, it’s one of the only car seats that can fit three across in a backseat.

You don’t need a huge SUV with the Clek Fllo!

This car seat does have a long lifetime, but the beginning of it is a little complicated. The seat on its own can’t be used until the child can sit up unassisted. For use before that, you have to buy an additional accessory, playfully named the “infant-thingy.”

You probably know it as a newborn insert. While the fabric is stain-resistant, don’t plan on throwing the cover in the washing machine. The cover cannot be removed and can only be hand-washed. One accident can turn this car seat into a messy nightmare.


  • Extended rear-facing capabilities
  • Fits 3 across in a car
  • Several colors and fabric styles


  • Requires infant insert for newborn use
  • Not machine washable

Safety Ratings

Clek does safety right. The company ensured it had the latest safety innovations in their car seats. In fact, the car seats’ design mimics an adult car seat, with a steel-reinforced frame and energy-absorbing crumple zones. Like in a car, these zones deform in the event of a crash to absorb the impact. Clek car seats have the highest rear-facing weight limit in North America.

Clek fllo head support

The company’s founders were inspired by Sweden’s car seat regulations. There, children rear face until they turn four. The Clek Fllo allows a child to rear-face longer than other car seats on the market. 

The Clek Fllo seat comes with an anti-rebound bar. Not a lot of car seats have this feature, but it’s a good one to have. The bar is found at the bottom of the car seat while in the rear-facing position. It prevents the force of the car seat rebounding toward the back of the vehicle in a crash.


Like all car seats, the Fllo’s expiration date can be found on the seat itself. On the bottom of the seat, you’ll find a sticker with the expiration date. Clek Fllo car seats expire 9 years from the date of manufacture


It can feel like we hear a new recall every day. It can be disheartening. Don’t despair though. If you are looking for something trustworthy, you need a Clek car seat. According to, no Clek car seat has been subject to any recalls, replacement part issues, or warnings as of this publication date. Currently, there are No safety recalls.


Clek offers a limited warranty. The warranty covers any defects in material and workmanship for one year from the date of original purchase. The Fllo car seat is eligible for an extended limited warranty.

To be eligible, the car seat must be purchased from an authorized Clek retailer and be fully registered online at within 3 months of the date of purchase. This extended warranty lasts for an additional two years. An original receipt will be needed to validate the warranty. Normal wear and tear will not be covered under this agreement.


While rear-facing and reclined, the Fllo measures 32.5 inches from the anti-rebound bar to the back of the seat. Its height is 27 inches. When forward-facing, it’s 31 inches tall. The seat is 16.9 inches, while the base is 13 inches. The car seat weighs 25 pounds. 

Colors and Styles

The Clek Fllo comes in eight different colors: Noire, Flamingo, Capri, Slate, Mammoth, Shadow, and Thunder.

It is also available in a fun print from Tokidoki called Reef Rider. The print was released in November 2019. It features whimsical characters in a seascape of an underwater adventure.  Clek has offered limited-edition Tokidoki prints for 6 years.

Honest Customer Reviews

Customers absolutely love the size of the Clek Fllo. This seat’s frame is narrow and is a major space saver.

It fits in even the tightest of back seats.

With two or more car seats, space is vital. Customers also like how sleek and modern these seats look. Clek designed these seats to have a distinctive look, and customers love it.

The more negative reviews are quick to mention the car seat’s weight. At 25 pounds, it’s certainly not lightweight. This, along with its complicated installation, makes it hard to move from car to car or car to airplane.
